Slauson sustained the injury during the Bears' loss to the New England Patriots on Sunday, though it isn't clear exactly when.

Michael Ola will likely start in Slauson's place going forward.

Ola has already filled in at left guard, left tackle and right tackle this season due to several injuries along the offensive line. Slauson missed three games earlier in the year due to a high ankle sprain, right tackle Brad Mills has dealt with a lingering foot injury and left tackle Jermain Bushrod missed two games due to a knee injury.

The games missed this year by Slauson have been the first absences of his career, as he started all 16 games each season for the New York Jets from 2010-12 and did the same last year for the Bears. He signed a four-year, $13.9 million extension with Chicago in January.
